“…However, it has been shown in Ref. [24] that this representation choice must be ruled out because it induces FCNC contributions that exceed the current experimental limits. The only way to evade these bounds is setting the Z mass above the 100 TeV scale.…”

“…In the Standard Model, FCNC processes are forbiden at tree level, they can occur through a weak interaction of second order mediated by the W boson [21]. Many FCNC investigations have been performed in the context of 3-3-1 models [22][23][24][25] (see Ref. [26] for supersymmetric models).…”

“…In particular, a recent analysis of FCNC processes in the RM331 model has been done in Ref. [24], however, only contributions coming from the Z have been taken into account. Here we plan to expand this investigation calculating the mass difference terms of the K 0 − K0 , D 0 − D0 , B 0 − B0 meson systems, including both scalars and gauge bosons contributions, as well as those coming from the SM mediated by the W boson using two particular texture parametrizations for the quark mass matrices, described in [22,27] (parametrization 1) and Ref.…”

In this work we overhaul previous studies of Flavor Changing Neutral Current processes in the context of the Reduced Minimal 3-3-1 model(RM331). We sift the individual contributions from the CP even scalars and the Z gauge boson using two different parametrizations schemes and compare our results with current measurements. In particular, studying the B 0 −B 0 meson system we find the most stringent bounds in the literature on this model, namely M Z 3326 GeV, M V ± 910 GeV, M U ++ 914 GeV and m h 0 2 889 GeV.

“…the resulting theory would be ruled out by the large FCNCs, provided that the new physics enters below the Landau pole. Furthermore, the theory would be invalid (or inconsistent) if one tried to push the new physics scale far above the Landau pole in order to prevent the FCNCs [9,21]. All these will also be studied in the last of this section.…”

Simple 3-3-1 model and implication for dark matter

We propose a new and realistic 3-3-1 model with the minimal lepton and scalar TeV and yield that the third quark generation is different from the first two. The correct mass generation for top quark implies that the minimal scalar sector as proposed is unique. By the simple 3-3-1 model, the other scalars beside the minimal ones can behave as inert fields responsible for dark matter. A triplet, doublet and singlet dark matter are respectively recognized. Our proposals provide the solutions for the long-standing dark matter issue in the minimal 3-3-1 model.

“…It was called reduced 331 model and some of its phenomenology was developed in Ref. [8]. Curiously, the scalar content that survives the reduction has the appropriate quantum numbers to be supersymmetrized, without the need of extra multiplets employed in the first SUSY versions of the minimal 331 model [9,10].…”

A supersymmetric version of the recently proposed reduced minimal 3-3-1 model is considered and its Higgs sector is investigated. We focus on the mass spectrum of the lightest scalars of the model. We show that Higgs mass of 125 GeV requires substantial radiative corrections. However, stops may develop small mixing and must have mass around TeV. Moreover, some soft SUSY breaking terms may lie at the electroweak scale, which alleviates some tension concerning fine tuning of the related parameters. The lightest doubly charged scalar may have mass around few hundreds of GeV, which can be probed at the LHC, while the remaining scalars of the model have masses at TeV scale.
